Specification of Iletters Patent.

Application filed May 16, 1907.

Patented June 18, 1912.

Serial No. 374,030.

Illinois, have invented certain new and useful improvements in Ovens, of which the follow-lug is a specification.

My invention relates to ovens and espe- ,ciall v to that class of bakers ovens having a rotary appliance for handling the product and commonly termed reel ovens.

The chief objects of my invention are to providean oven ot the type designated that will facilitate the handling of the material 5 inserted therein and the removal of the finished product; to produce an oven of such design that. the heat will be easily distributed, andto furnish the usual non-coir ducting material to prevent radiation and 2 conversion of the heat and thus maintain a uniform degree of temperature throughout the structure.

Further objects of my improved oven are to furnish convenient appliances for regulaling the necessary valves and dampers,

and to provide the main feed and discharge opening with a balanced door that will retain its position when opened or closed.

I accomplish the above and other minor results by the apparatus illustrated in the accompanying drawings which form a part of this specification, and in which Figure l is a sectional elevation of an oven embodying my improvements taken on a longitudinal median plane; Fig. 2 is a similar view taken on a transverse planegthe reel having been removed; Fig. 3 is a seclional view on a horizontal plane cutting the lire box. and Fig. i is a. horizontal section through the upper portion of the oven, the

flucs bcin; shown in full.

Referring to the drawings in detail the numerals 5 and (3 indicate the front and r'car walls, respectively, and 7 the side walls 4, of a rectangular oven preferably constructed of brick. which present the desirable physical property of heat non-conduclivity pro- (luring a durable structure calculated to re tain the heattor a consiiilerable time ata 5m unil'orm temperature.

lire box H is located in the center of the front and furnished with grate bars 9, a door It) and an ash pit ii. horizontal partition 12 extends over the whole urca of the structure and forms a floor for the heat.

ing chambcr i l in which is located the reel.

This is hung upon a shaft 14: journaled in. the side walls of the oven and arranged for the application of power in any convenient manner. The reel may be of any of the well known forms, the structure shown consisting of two sets of radiating; arms 15 only one of" which is shown secured to flanged boxes, 16 and connected by ties 17. The extremities of the arms are connected by rods 18 upon which are hunp; the baking trays 19.

The baking chamber is provided with the usual feed and discharge opening 20 for which is provided a closure 21 furnished with a counterbalance 22. At. the rear of the fire box is the main flue 23 which extends horizontally back to the wall and counnunicates with a chimney flue 2st, the opening being closed by a damper 25 which is n'ianipulated by a eable or chain 26 extending through a pipe 27 to the front of the oven. Extending parallel with the side walls of the oven are partitions 28, 29, which are duplicated upon each side to form passages or tlueslll); 31, which communicate with each other and with the central line by openings 32, 39. At the rear ends the out.- side lines 31 communicate with vertical tines 33 preferably formed of brick and extenth ing into the baking chamber These fines are directly connected at their upper ends with a series of lines 34-, Ill, rectangular in cross section preferably formed of sheet metal and spanning the baking chamber in a series of parallel arches. There are four of these arches, the two lying externally being in communication on the side oi? the oven opposite to the said times 33, through a breeching 35 with the adjacent middle arch, and the latter in turn communicate at 36 with each other. and finally open into the chimneyflue 24 through an orifice 37 which is controlled by a damper 38 which has suitable operative connection with a. handle 39, placed atthe front of the oven for convenience. 'lhis arching arrangement of the lines which are thus distribulcijl approximately over the whole area of the baking chamber insures a complctcand uniform distribution of the heat and as the urchcd root thus formed is brought into close relationship with the upper half of the reel, the boat will be applied in the most dcsiral'ilc and economical manner. .is a still further means of confining -ind as 2 result econo mixing the heat a covering of non-conduct ing material 410 is supplied to the roof of the oven. This may be constructed of'a single layer or of superimposed layers of difierent materials and asbestos or other cellular substance may be employed for that purpose,

Having thus described my invention What- 1 claim as new and desire to secure by Letters Fatent, is i A baking oven, including a baking chamber, means for heating said chamber and a chimney, a series of inner and outer dues for the products of combustion, said flues oaaeee in the presence of two witnesses.
